- use `requestAnimationFrame` and related techniques to minimise scroll processing
- add an `isLoading` guard to ensure we don't try to process anything until the next page has been loaded+inserted
- check for a 404 as an indication we've loaded as many pages as possible at which point the scroll behaviour is removed
- sanitize `window.location.pathname` to remove hash params and any double-slashes that may result
- add a 100px buffer from the bottom of the screen so that it's not necessary to exactly hit the bottom before infinite loading is triggered
Declared all jQuery objects once where needed instead of diving into the DOM multiple times for the same object.
Added style consistency between variable declarations, if/else statements and functions.
